DOOR-CONTROL MECHANI'SM.

Application led November 10, 1923.

My invention is an improved door control mechanism, particularly applicable to garage doors.

The object of my invention is to provide a door control which is simple in construction and effective in operation.

Another object is to provide a control which is operated by the automobile from both the inside and outside of the garage.

Further objects and advantages will be more specifically pointed out and described in the following detailed description.

In the annexed drawing in which my invention is illustrated:

Figure 1 is a front elevation of a garage employing my control and with parts broken away to show the interior structure.

Figure 2 is a sectional view taken on the line 2 2 of Figure 1.

Figure 3 is a View similar to Figure 2, but with the tilting plates removed.

Figure 4 is a sectional view taken on the line 4 4 of Figure 1.

Figure 5 is a sectional view taken on the line 5 5 of Figure 4.

Figure 6 is a side view of one of the tilting plates.

Referring more particularly to the drawing: the garage 1 has doors 2 and 3 mounted in the front thereof which are operated by my contro] mechanism.

My control mechanism comprises a pair of of tilting plates 4 and 5, which are set approximately at the level of the floor of the garage, partly in front of and partly within the garage. Each of these plates has bearing plates 6 and 7 depending from their lower sides, which. straddle shafts S or 9 supported in blocks 10 or 11 respectively. These blocks rest on a sub-floor 13a. Thus it will be seen that the plates 6 and 7 may rock on the shafts 8 and 9, which will be further described. Springs 13 and 14 are secured to the lower faces and adjacent the abutting edges of the plates 4 and 5, and are also secured to the subfloor 13a thus tending to pull the adjacent edges of said plates downwardly. Outwardly extending channeled arms 15 and 16 are formed on the plates 4 and 5 respectively, in which the doors 2 and 3 are adapted to travel. Wheels 17 and 18 are journaled in the bottom of the doors 2 and 3 respectively, and are adapted to slide in the arms 15 and 16. The upper part of the doors 2 and 3 extends into a slotted Serial No. 673,948.

guide plate 19, which extends across the front of the garage 1, and is secured thereto. Locking bars and 21 are pivoted to the doors 2 and 3 respectively and are adapted to travel in channeled plates 22 and 23 respectively, which are secured to the floor of the garage 1. Each of these plates has an opening 24 formed therein, through which the ends of the bars 2O and 21 are adapted to drop and thereby lock the doors 2 and 3 in the closed position. Then the bars 20 and 21 project through the openings 24, they rest upon releasing lingers 25 and 26 respectively which are pivoted on the subfloor 13a under the outer edge of the plates 4 and 5 respectively.

The automobile is driven upon the plates 4 and 5 which causes the outer edges to tilt downwardly, and engage the releasers 25 and 26, which in turn raise the locks 20 and 21 and permit the doors to roll outwardly upon the arms 15 and 16. When the automobile is removed from the plates the springs 13 and 14 pull the inner edges downwardly, which allows the doors to roll inwardly to the closed position, and the locks 20 and 21 fall into place to lock the doors.

Having described my invention I claim: 1. A door control comprising a tiltable plate, and a track on said plate in which the fr door is adapted to roll, a locking bar pivoted to said door, a plate over which said bar is adapted to travel, said plate having an opening therein into which said bar is adapted to fall and lock the door in the closed position7 means to raise said bar to open said door, and a releasing linger pivoted under said plate and adapted to support said bar, said plate being adapted to engage said linger and raise said bar to unlock the door.

2. A door control comprising a shaft, a plate tiltably mounted on said shaft and adapted to receive a vehicle wheel, a track on said plate extending perpendicular to said shaft and adapted to receive a sliding door, a locking bar pivoted to said door for locking it, and means operable by the weight of said wheel to raise said bar to allow the door to open.

3. A door control comprising a shaft, a plate tiltably mounted on said shaft and adapted to receive an automobile wheel, a track on said plate extending in a direction perpendicular to said shaft and adapted to receive a sliding door7 n looking bar pivoted to said door, a plate over which said bar is adapted to travel, said plate having an opening therein into which said bar is adapted to `fall and lock the door in the closed position, means To raise said bar to open 'said door, and a releasing finger pivoted under said plate and adapted to support said bar, said plate being adapted to engage said finger and raise said bar to un- 10 lock the door.

ln testimony whereof I affix my signature.

THOMAS J. OWENS.
